Chinese Shanghai Electric purchases German aircraft equipment manufacturer Broetje-Automation

Chinese companyShanghai Electric is purchasing a German aviation equipment manufacturer Broetje-Automation for €170m. European assets that grow cheaper are more and more frequently acquired by Chinese companies.  

I remember a book on management which read that technical knowledge can be obtained either through creation of ones own research and development centres, or through the acquisition of foreign companies that already own relevant knowledge and technology.
